[xmonad] zaphod mode

[Martin Carroll]

Ok, let me clarify my earlier inaccurate statement about CRTCs.  
Consider a computer with one physical GPU that has two physical video 
ports.  That physical GPU has two physical CRTCs attached to it.  In 
both zaphod and nonzaphod mode, the host runs one instance of the Xorg 
process.  The difference is that in nonzaphod mode, Xorg "presents" one 
GPU with two CRTCs, whereas in zaphod mode, Xorg "presents" *two* GPUs, 
each with a single CRTC.  I want to run xmonad in the latter mode.

Mike correctly pointed out that the "obvious" way to run xmonad in 
zaphod mode is to change /etc/X11/Sessions/xmonad to the following:

         DISPLAY=:0.1 xmonad &   # Managing screen 1
         DISPLAY=:0.0 xmonad     # Managing screen 0, exit to exit X.

Unfortunately, that doesn't work.  Mike points out that some finagling 
might be necessary to get this to work, but after several hours I was 
unable to find the right finagling.  I *conjecture* that xmonad does not 
support zaphod.

If anyone on this list has managed to get zaphod to work, please let me 
know.  Thanks!
